What is absolute zero on the Kelvin scale = on the Celsius scale?
-273.15C

-273.15C

Convert Celcius to Kelvin:

?K = (C + 273.15C)x 1K/1C

?K = (C + 273.15C)x1K/1C

Regardless of magnitude, all numbers can be expressed as:

N x 10^n

N x 10^n

Scientific notation:
If the decimal is moved to the left, it is a ____integer.
If to right, it is a _____interger

Left ---positive integer

Right ---negative integer

T/F
In significant figures, it is assumed that the last digit is understood to be "uncertain"

T

Rules for Significant Digits:
- Any digit not a zero is significant.
- Zeros between nonzeros significant.
- Zeros to left are NOT significant.
- Zeros to right significant
- Trailing zeros (after last nonzero digit) may/may not be and needs scientific not.

significant digit rules

Add/Sub, answer cannot have more digits to the right of the decimal point than either of original numbers

T

Round-off procedure:
- Drop digits if less than 5
- Equal or greater than 5, round up

T

Mult/Div: #of signficant figures determined by the original number that has smallest # of signficant figures

T

Exact numbers obtained from definitions (eg 1ft = 12 in), or by counting # of objects ---- considered to have an infinite number of significant figures

T

Accuracy:
How close a measurement is to the true value of the quantity measured.

Accuracy

Precision:
How closely two or more measurements of the same quantity agree with one another.
